摘　　要：目的了解2012年东莞市霍乱等重点感染性腹泻的流行特征及流行优势毒株的分布，为预防控制霍乱等重点感染性腹泻提供参考依据。方法对2012年霍乱等重点感染性腹泻的症状监测和病原学监测结果进行流行病学分析。结果东莞市2012年腹泻病例占门诊就诊病例总数的4．15％，10—12月为流行高峰；全年病原检测阳性268份，阳性率为31．98％，病毒性腹泻病原呈现明显季节性，10-12月以轮状病毒为优势病毒，2-9月以诺如病毒为优势病毒；对腹泻病例占门诊就诊病例总数的比例与病原学检出率进行秩相关分析，相关系数为0．66（P〈0．05），呈正相关关系。结论东莞市腹泻流行呈现秋冬季高峰，流行优势毒株随季节变化而变化，0～岁年龄组婴幼儿是病毒性腹泻感染的重点人群。Objective To understand the epidemiological characteristics and distribution of epidemic strains of cholera and other key infectious diarrhea in Dongguan in 2012 and provide evidence for the prevention and control. Method The epidemiology analysis was conducted on the data of symptom and etiological surveillance of cholera and other key infectious diarrhea in 2012. Results The proportion of diarrhea cases was 4.15%. The epidemic peak was from October to December.The pathogens were detected in 268 samples, with a positive rate of 31.98%.The viral diarrhea showed obvious seasonal pattern.The prevalent virus was rotavirus from October to December,and norovirus from February to September.The proportion of diarrhea cases and the total outpatients clinic cases was positively correlated with the detection rate of the pathogen （correlation coeffieient：0.66,P〈0.05）.
